Abstract
A thermostat at a temperature of 33.50 °C was constructed for noise measurements on electronic devices for periods of days. A stabilization factor with respect to room temperature fluctuations of over 4×104 is achieved. Upper limits are determined for stray magnetic field fluctuations as ‖Ḃ‖⩽0.3 μT/sec, and for electric fields as ‖E‖⩽8 μV/m, measured in the frequency range 10−4 Hz <f0 Hz. Long‐term drifts of temperature are estimated as ‖δT/δt‖<100 μ°C/day. We consider this instrument a medium stable, thermally, electrically, and magnetically quiet thermostat suitable for long‐term investigations of basic fluctuations in device properties.Keywords
